Her immediate relatives have urged the producers of I'm A Celebrity... Get Me Out Of Here!' to reveal why the 24-year-old has been excused from certain Bushtucker trials, following the public's negative reaction.

"We have been sworn to secrecy," Rebecca's uncle Tony told the Daily Mirror. "Becky wants the public to know why she is being excused. We wish the producers would say the reason."

Rebecca's aunt, Sonia, also revealed that despite the medical issue having ruled her out of three Bushtucker Trials so far, the swimmer is keen to take part in them.

"It's not Becky's choice," she said. "She wants to do the challenges - even eating grubs - but she is not allowed to do some of them on doctor's orders."

It's prompted rumours that Rebecca is either pregnant or suffers from claustrophobia, but last night she was finally allowed to take part in a group trial called Roach Trip.

Along with her campmates Annabel Giles, Joey Essex, Alfonso Ribeiro, Matthew Wright and David Emanuel, Rebecca had to spend 90 minutes in the total darkness on board a jungle coach in a bid to win stars for dinner.

However, it seemd that the nature of the trial was claustrophobia, and therefore that may not be the reason why Rebecca hasn't been taking part in the trials.

Instead, viewers believe that Rebecca's serious medical condition could be a form of asthma, which she has previously admitted to suffering from.

"I've had asthma since I was little," she's said in the past. "My type is exercise-induced and it's common in swimmers."

The outcry from viewers, who suggested that Rebecca should quit the show, prompted her fiance Harry Needs to defend her on his Twitter page yet again.

"First things first, exemption from trials isn't a choice by the celeb but by the doctor #clearingtheair," he wrote.

"Trust me @BeckAdlington is a tough cookie, she would be up for and give anything a try... She eats bovril for crying out loud!"

His words were echoed by Rebecca's sister, Chloe, who is in charge of the athlete's Twitter account whilst she's in the jungle.

"For everyone asking all I can confirm is that it is only the doctors that can decide who can do each trial," she posted.

"Becky and the other celebrities aren't aware what the trial is each day, it's the doctors who rule out the contestants."

Chloe also repeated what her aunt Sonia had said, by adding: "Even we don't know what the medical grounds are. Becky was in good health when she left and definitely isn't pregnant!"
